I disagree. He tries hard, he studies well, and he has the better release when things go well. He's not a 'gamer'. He doesn't throw the ball well on the move, or when he can't get his feet set. Doesn't turn his hips well. Obviously not a playmaker at running the ball, though I still say he handles that part well enough.
Its never been about one passing the ball better vs running the ball better. Martinez is the more natural player, Gebbia is stiffer but more polished. Either will get the job done.
